A new trophic status monitoring method for freshwater lakesthe chlorophyll ratio model
|
Abstract:
The ratios of chlorophyll (chl) b/a and c/a in algae,including Microcystis aeruginosa,Anabaena sp.,Chlorella pyrenoidosa,Nitzschia hantzschiana,Glenodinium pulvisculus and Prymnesium parvum,were measured through spectrophotometry.The ratios of chl b/chl a and chl c/chl a of mixed algae in waters with different trophic status were calculated according to the different algae population compositions.The relationship between these ratios and the water trophic status were analyzed.The results showed that when th...
